This much-anticipated survey of John Chamberlain’s work, the first in a U.S. museum since 1986, unexpectedly became a memorial show when the giant of postwar American art died in December, at 84. Nearly 100 pieces will be on view, including dozens of his signature crumpled-metal sculptures made using salvaged automobile fenders, hoods, and roofs, as well as examples of his diversions into painting, photography, and sculpting with foam, resin, and foil. Blending an Abstract Expressionist bravado, a Minimalist affinity for industrially fabricated materials, and Pop references to this country’s beloved car culture, Chamberlain’s work is about as quintessentially American as it gets.February 24–May 13; guggenheim.org
